摘要
一般机组设计启动过程采用电动给水泵完成机组启动前期的锅炉给水工作,由于电泵是耗电大户,增加了厂用电率。用汽动给水泵代替电动给水泵完成机组启动全过程锅炉给水的工作,有效地降低机组启停阶段的厂用电耗,从而达到节能的目的。
Unit to start the process of designing the general use of electric pumps to complete the unit of the boiler feed water pre-start work,as the pump is large power consumption,an increase of the rate of plant consumption.Used in place of steam-driven pumps to electric pumps to complete the unit to start the whole process of the work of the boiler feed water,effectively reduces the unit commitment stage of the plant power consumption,so as to achieve energy-saving purposes.
